Why do cat's eyes have cat eyes?
The opal is highly regarded because it has a cat's eye similar to that of a cat's eyes. The eyeliner in the center of the arc of the opal will appear in the sunlight, which makes people more and more attracted by the mysterious opal. Then friends know why cat eyes have cat eyes? What is the principle of this? The cat's eye has a cat's eye because the inside of the opal has a very rich inclusion. These inclusions are needle-shaped and tubular. Once the light illuminates such a gemstone, the inclusions are reflected. Because the opal is curved, it can be like a lens to gather the reflected light into a bright line. This bright line is the cat's eye we see. When we turn the opal, the position of the reflected light changes with the angle of the light shining on the inclusion, so we feel that the cat's eye is turning. The study found that the cat's eye bright line and its inclusions are arranged equally in two directions. We can see that the bright lines are two crossed, giving the impression of starlight. If they are arranged in three directions, then it looks like a starburst. The above is the answer to the cat's eye why there is a cat's eye. I believe that friends have a certain understanding after reading it. There are many kinds of gemstones with cat eyes in the gem world. In addition to the gold-green cat eyes we know well, there are also tourmaline cat eyes, quartz cat eyes, glass cat eyes and sea blue cat eyes. However, only gold emeralds are called opals, others must add their own names before the cat's eyes.
